I was in Stormwind yesterday after handing in a few quests & repairing etc. & thought I better check the AH 'cause the rogue i am slowly leveling had hit 35 & a gear update might be in order.
I stepped out side the AH & there was a level 27 human warlock there. Ding level 28. Ding level 29. Ding level 30. Ding level 31. This went on as a bigger & bigger crowd gathered.
She finally said after she had passed level 51 "Leveling is so tiresome" & logged. I think she hit level 57 before she finally dissapeared.
There were a LOT of "how did she do that" questions & then the accusations started-Hax-should be banned-report her etc.
After a while some one said its the recruit-a-friend system. Apparently if you recruit someone & pair with them you gain levels much faster & can somehow "award" experience/levels to the player who recruited you. This is for a preset period.
It was quite theatrical & obviously planned by the players who did it. It would probably leave something of a sour taste in a few peoples mouths. I know i was unimpressed to watch a player effectively jump form well below mine to about ready to hit outlands in a few seconds.
It also shows that things are not always as they seem.
